Serial No. 236,086.

This invention relates to an improvement in printing telegraphs in whicha transmitter is employed in connection or cooperation with any numberof recording machines which record the characters sent out by thetransmitter, and the invention has for one of its objects, the provisionof an improved mechanism whereby the recording machines may be broughtautomatically into unison as often as desired.

In printing telegraphs as now constituted, the operator at thetransmitter is supposed to operate a key or switch at intervals whichwill bring about a unisoning of the recording machines, but in actualpractice, the operator sometimes fails to do this with the result that arecording machine once out of unison may remain in that condition for anextended period.

By the present arrangement we have pro vided a constructionwhereby theunisoning of the machine is brought about by the clos ing of apredetermined circuit, effected in the present instance by manipulationof the period or spacer key on the transmitter, and inasmuch as this keyis depressed very frequently by the operator of the transmitter, it willbe. obvious that the recording machines will be brought to unison atsufficiently short intervals to make our apparatus practicable.

In the operation of machines of the character with which the presentinvention is con cerned the current employed is reversed in polarityautomatically for the purpose of effecting operation of escapementmagnets constituting a part of the recording machine, the operation ofthese magnets causing the escapement mechanism which controls therotation of the shaft carrying the type wheels to function. To operatethe impressing mechanism of the receiver, an impress magnet is employedoperative when the transmitter shaft has been brought to rest, at whichtime current of one polarity only is flowing through the line. In thepresent invention, resistance normally in series with the escapementmagnets, is adapted, when the machines are to be brought to unison, tobe shunted on the closing of a predetermined circuit as by the operationof the period or,

spacer key of the transmitter, whereby the operator, in the normal andordinary operation of the transmitter will unison the recording machinesintermittently although not necessarily at regular intervals.

In the accompanying drawings wherein an embodiment of our invention hasbeen illustrated,

Fig. 1 shows the same in side elevation;

Fig. 2 is a plan View of the apparatus of Fig. 1;

Fig. 3 is a view similar to Fig. 2, this view being taken at rightangles Fig. 2;

Figs. 4., 5, 6 and 7 are detail views; and

Fig. 8 is a wiring diagram.

Our improved apparatus comprises scape wheel 1, and escapement pawl 2adapted to be vibrated in the usual Way by the armature 3 of escapementmagnets 4. and 5. These magnets, as is well known, effect a vibration ofthe armature 3, because of a reversal of the polarity of the currentpassing through the magnets, this reversal of polarity being effected bypolar relay 6, (see the wiring diagram of Fig. 8) The scape wheel ismounted upon a rotatable shaft 7, which shaft carries also a worm 9, anda unisoning arm 10, the latter extending at right angles to thelongitudinal axis of the shaft and being provided at its outer end witha cam face 11. Pivotally secured to the frame of the machine as at 12,for example, is an arm 13 which extends toward the type shaft 7 so thatits inner end overlies the same, this end of the arm being provided witha portion 14 adapted to cooperate with the worm 9. The portion 14 isprovided with a stop pin 15, extending laterally with respect to thearm, thls pin being disposed at right angles to the plane of rotation ofthe unisoning arm 10 heretofore re ferred to. Attached to the stop arm13 is a spring 16 anchored to the frame of the machine at 17, thisspring tending to draw the outer end of the arm 13. i. e., the endcarrying the stop pin 15 to the right, as shown in F g. 3. for instance,and into engagement wlth the worm 9.

The escapement magnet 5 has its poles extended as indicated. at 18, forcooperation under certain conditions with an armature the magnet 5,while the outer end is provided with upwardly extending portion 23 lyingbeneath the end of the pivoted arm 13.

As above explained, the purpose of this wholezginvention is to providecomparatively simple'lneansfon .bringing the recording vmachines intounison with the transmitter, consequently it is possible by ourconstruct-ion, to stop the rotation of the type shaft 7 periodicallywith the deliberate intention of unisoning the machines. The stopping ofthe type shaft? is brought about by interpl sing the pin 15 in the pathof the arm 10, carried by the type shaft.

lVith reference now to the wiring diagram ofFigQ 8, we have illustratedtherein vdiagrammatically ,a, transmitting machine comprising the usualsunflower or stationary commater-24', trailer 25 cooperating therewithand mounted, on a trailer shaft 26, which is geared to the transmittershaft 27, magnetic clutch 28,=keyboard 29, and relay for the clutch.,Thekeyboard is, shown asprovided with two heys32 and 33, but it will beunderstood, of course, that in practice it is provided with the usualnumber of keys for controlling the transmitter.

' In the operation of the machine, with the transmitter, shaft 27 inrotation the, polarity of the c rrent passing through the escapernentmagnetstand 5 isrever sed in the usual way bylth e provision of thebrushes 34:, 35 3.1 1d 36, cooperating with the polar .relay 6 to effectvibrationof the armature 30f the escapenaent magnets of the receiving.instrunient, see ig. l1), and aLresultiriglvibration ofthe escapeinentpaw 1,2 to permitthe scape wheehl'to rotate in an inter nittentfashion.Whentheliey' 32, foriristancdofthe trans- H tt ybo d' Qp i te i a ei filii is cl d I tothejclutchrelay 30; the arma ture 37 g of thisre'laiyhis operated to close circuit to the magneticclutch 28, theclosing of thiscircui t arresting the rotation of the transmitter shaftUnder these conditions the impress magnet31 of the receiving instrumentwill operate t'o effect operation of the impress mechanism to make thedesired impression. In the operation of this apparatus, the end ,lfl ofthe ,13 ,(Fig. .will lie upon the wormfil and inasmuch as the same isrotatingintermijttently by,the action of thesecapementmechanism, thearmwill be moved tethaleftby the actionof the wormtoward theseape wheeltothedotted line position, for example, shown inFig. 7. Assuming thatwhen thearm 13 has reached the position shown inFig. 7, the period key33 is depre sedithe ele ma 38 ,(F Will receive current so, as (to shuntresistance 39 which, up to this time, has been in series with theelectromagnets 4 and 5. Of course, the depression of the period orspacer key 33 will also close the circuit to the magnetic clutch 28, aswill be understood, so that the polar relay 6 will no longer beoperative and a current of only one polarity and of increased amperagewill flow through the magnets 4; and 5, and this increase in currentwill cause the magnet 5, toattract the armature 19 (see Fig. 4). Theswinging of the armature 19 about its pivot will raise the inner end ofthe arm 13 as shown in Fig. 4, so as to lift the end 14- out ofengagement with the worm 9 on the type shaft and the spring 17 which hasbeen placed under some tension due to the movement of the arm 13 to theleft, as viewed in Fig. 3, will draw the end of this arm to the right,as viewed in the same figure, in a ,direction away from the scape wheel1 and toward the unisoning arm 10. If the machine is in unison, as thearm 13 is moved toward the unisoning arm 10, the latter will be in theposition shown in F ig. 6, i. e., in such a position that the stop pin15 as the arm 13 drops downward will strike the cam face 11 on theunisoning arm 10 and this face will cam the arm 13 to the left again, asviewed in Fig. (5, until the arm is free to fall upon theworm 9 to againresume its normal travel toward the scape wheel. In other words, if themachine is i n..unison with thetransmitter, upon the depression of thekey 33 the unisoning, mechanisnrwill have no effect upon the type shaft7. If, however, the machine should be out of unison, the unisoning arm10 will be, in such a position when the end14 of the arm-13 is nioved tothe right, as viewed in Fig. 7, that the can'i facell will not beeffective to move the pin 15. andarm13 toward the scape wheel and thepin 15will remain in the path of-the unisoning arm 10 to preventrotation of the type shaftT. The type shaftTwill remain stationary untilthe PGI'lOCl-Ol spacer key 33 is again, depressed at whichtime, ofcourse, the transmitting machine andthe receiving machine will be inunison. The depression oftheperiod or spacer key33the second time will,of course, raise the end 14 of the arm 13 and inasmuch as the unisoningarm 10 isnow at the pin 15, thepin .15 will be raised into engagementwith the cam face 11 on the arm 10, and-this unisoning arm now beingfree to rotate, it and the type shaft will rotate in the direction ofthe arrow on Fig. 7, and the face 11 will cam the arm 1.3110 the leftout of thepath of thearm 10 entirely, and the end It ofthe arm 13-willfall upon the worm 9 to resume its normal travel to the left or towardthe scape wheel.

It will be seen, therefore, that we have provided an apparatus for usein connection with printingtelegraphs whereby the receiving machine maybe broughtto unison by the closing of a predetermined circuit, it beingunderstood that depression of the spacer key for this purpose has beenshown for purposes of illustration only. It is to be understood alsothat if desired, means other than the escapement magnet may be providedfor disengaging the stop arm from the worm or other means on the typeshaft. It will be seen also that the unisoning mechanism is capable ofarresting the rotation of the type carrier shaft when the machine is outof unison but is carried automatically out of shaft arresting positionif the machine is in unison. Likewise it will be apparent that meanshave been provided whereby when the type.

shaft has been stopped by our unisoning mechanism, and the machinebrought to unison, the mechanism is then operative to permit of the typeshaft resuming its rotation.
